The regularity of the four time-harmonic vector fields composing any strong solution of the system obtained from Maxwell's curl equations and the constitutive relations in the interior of an inhomogeneous bianisotropic material are investigated. The

A comparison between stand-alone and distributed architectures for spectrum hole detection

Autor: Luca Bixio, Carlo S. Regazzoni, Mirco Raffetto, Marina Ottonello

Publikováno v: WCNC

In this paper two different cognitive radio architectures, i.e. stand-alone and distributed, are proposed for spectrum sensing purposes. In particular, both architectures implement a fast and reliable algorithm based on cyclic features extraction whi

Publikováno v: CrownCom

In the last couple of decades, the introduction of new wireless applications and services, which have to coexist with already deployed ones, is creating problems in the allocation of the unlicensed spectrum. In order to overcome such a problem, by ex
